simple audio mixer circuit with fet 2n3819

This circuit, a simple mixer circuit.It can mix two signal channels and one channel is output.Using a codec circuit,Convert stereo audio to mono audio time.
It can increase the number of channels too. By adding a VR1, R1 and C1 to the amount needed. Then connected to Buffett a new one.Most importantly is eating circuit current is very low.Can use with 9-volt batteries immediately.
When entering voice signal, one of input 1 and input 2. Audio is via C1 and C2 of each channel,served coupling signals to VR1 and VR2. To adjust the audio to the Fet Q1.Which it serves, including audio. Then expand signal the output pin S through C3 For coupling signal again, before leaving to the output.

Audio Mixer by FET 2N3819

This circuit be Audio Mixer Circuit by FET 2N3819 numbers, build easy and the a little equipment. By this circuit lets to use the microphone since two go up or use other tool all right wasp suit amplifier same microphone. The R1 and R5 will control value reduction input each beside. Thus R1 , and , R3 be the controller equilibriums.

Easy Audio Mixer by LM837

The mixer itself is a fixed-gain summing amplifier based on an LM837. It sums up all the six microphone preamp signals into a single output. This is called the MIX OUT, and is a rear-panel socket. The single output is split into two outputs, to allow easy connection to external stereo equipment. The idea behind this is to allow connection of an external effects unit or graphic equalizer between the mixed output and the power amplifier.
